can affect the growth of plants. They threaten biodiversity‚ agricultural yields‚ trade‚ and the agricultural environment. It is important to know that most insects are beneficial rather than destructive. Some insects play an essential role as pollinators of flowering plants just like the bees and butterflies. Some of the products derived from insects are honey‚ beeswax and silk. Despite of this fact‚ we cannot simply ignore it knowing that the number of beneficial insects is greater than the number

Synapomorphy- Is a trait that is found in certain groups of organisms that exists in no others. It is a homologues trait that exists in no others. Some synapomorphy are: lactation and fur in mammals. Monophyletic group- Consists of an ancestral population‚ all of its descendants and only those descendants. Paraphyletic- An evolutionary unit that includes an ancestral population and some‚ but not all of its descendants. They are not meaningful units in evolution. Polytomy- Term for internal

My project was over the tropical rainforest biome. The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50-260 inches (125-660) cm of rain falls yearly. A tropical rain forest has more kinds of trees than any other area in the world. Scientists have counted about 100-300 species in one 2 ½ acre area in South America. Seventy percent of the plants in the rainforest are trees. There are a couple of topics that can be discussed within this biome such as

they go extinct then we lose a lot of food and the ecosystem will be out of balance. Bees do a lot for the ecosystem‚ the main thing that they do is pollinate. “Pollination is essentially plant reproduction. Without help from animal pollinators‚ our everyday food supply would look much different– at least one third of our staples we’ve come to rely on would no longer be available”(Tucker). Bees pollinate by going to flowers and plants to get something out of them for themselves which could

Since 1969‚ Tu Youyou‚ a pharmaceutical chemist in China‚ collected 2‚000 folk remedies and ancient texts on the purported cure for malaria‚ a life-threatening disease caused by plasmodium. After years of research‚ she discovered a possible active ingredient that looked to inhibit the plasmodium’s growth in animals. Since then‚ this semi-synthetic substance‚ artemisinin‚ has saved millions of lives. Traditional knowledge‚ access to genetic sequence information and synthetic biology made this possible;

While sitting outside on a sunny day‚ I saw bees flying around me. I quickly got up and started to walk away. I was a little angry they had ruined my peacefulness. I muttered to myself “I wish bees would die.” A few months later in my biology class‚ we had to read an article about Honeybees and how they pollinate. I was very interested in how these insects contribute to our world. In the article‚ it also mentioned about the bees vanishing. I instantly desired to get this important information out
